<u>Answer:</u>

The angle between the ladder and the ground is 78.78\°

<u>Solution:</u>

It is given that the length of the ladder is 36 foot and the distance between the base and the ladder is 7 feet.

Here we can see that the hypotenuse is 36 foot and the base is 7 feet. To find the angle between the ladder and the ground we take the cos inverse of \frac{7}{36}.

Let the angle between the ladder and the ground is ‘x’.

We know, cos x = \frac{base}{hypotenuse}

\Rightarrow cosx = \frac{7}{36}

\Rightarrow x = cos^{(-1)} \frac{7}{36}

\Rightarrow x=78.78\°

Point P partitions the directed segment from A to B into a 1:3 ratio. Q partitions the directed segment from B to A into a 1:3 r
olga2289 [7]

Answer:

c)No, P is the distance from A to B, and Q is the distance from B to A.

Step-by-step explanation:

Point P partitions the directed segment from A to B into a 1:3 ratio.

Ratio is 1:3

So AP is 1  and PB is 3

Q partitions the directed segment from B to A into a 1:3 ratio.

Ratio is 1:3

So BQ is 1  and QA is 3.

That is AQ= 3  and BQ= 1

The ratio of Q and P varies

AP =1  and AQ=3

So P  and Q  are not at the same point.

Because P is the distance from A  to B  and Q is the distance from B to A

For the function f(t) = Pe^rt, if P= 6 and r = 0.06, then what is the value of f(6) to the nearest tenth? A. 219.6 B. 8.6 C. 0.1
Ann [662]
<span>B. 8.6 Let's substitute the given values into the function and calculate the result. So: f(t) = Pe^rt f(t) = 6e^0.06t f(6) = 6e^(0.06*6) f(6) = 6e^(0.36) f(6) = 6*1.433329415 f(6) = 8.599976487 Rounding to the nearest tenth, gives: 8.6 So the answer is "B. 8.6"</span>

in the drawing six out of every 10 tickets are winning tickets of the winning tickets one out of every three awards is a larger
Dafna11 [192]

Answer: P(\text{a ticket is randomly chosen will award a large prize)}=\frac{2}{21}

Since we have given that

Total number of tickets =10

Number of winning tickets =6

\text {Possibility of getting a winning ticket }=^{10}C_6

In which one out of every three awards is a large prize

so,

\text{ Possibility of getting a large prize }=^6C_3

Now,

P(\text{a ticket is randomly chosen will award a large prize)}=\frac{^6C_3}{^{10}C_6}\\\\=\frac{20}{210}\\\\=\frac{2}{21}

P(\text{a ticket is randomly chosen will award a large prize)}=\frac{2}{21}
